When Tazzie was first diagnosed with bone cancer I looked into K9 Immunity and CAS Options but due to her large size I decided that the number of pills I would have to give daily and the cost of the product was unreasonable so I just have her on fish oil, Vitamin C, etc. When my other dog Kona (65#) was diagnosed with a different cancer I looked into it again and my holistic vet recommended a product called Health Concerns Power Mushrooms, which is similar to K9 Immunity but much cheaper. A bottle of 50 costs $8.95 and since this is a human product even a large dog like Tazzie only needs 2-3 tabs twice daily. Much more in line with what I can afford and not too many pills!

I did a quick search on VIN and found that most holistic/alternative vets use this product for any cancer and it is very safe and a trustworthy company with pure products. If your dog is currently getting chemo I would ask your oncologist first but I know that it is compatible with metronomic chemotherapy
